Abstract
This suspension device is provided with a shock absorber () that is capable of altering damping force using the position of a piston rod () such that at least any one of the following characteristics are achieved, namely, first characteristics in which, within a range where the piston rod () is extending out from a cylinder () beyond a first predetermined position, the extension-side damping force is in a soft state and the compression-side damping force is in a hard state, and second characteristics in which, within a range where the piston rod () is retracted inside the cylinder () beyond a second predetermined position, the extension-side damping force is in a hard state and the compression-side damping force is in a soft state; and an operating force adjustment mechanism that is capable of adjusting at least one of the operating force in the roll direction of a vehicle, and the operating force in a pitch direction of the vehicle.
